The oldest elephants wandering Mozambique’s Gorongosa National Park bear the indelible markings of the civil war that gripped the country for 15 years: Many are tuskless. They’re the lone ...

Female elephants, that is. What no one has seen in the park is a tuskless male. “We had an inkling,” said Shane Campbell-Staton, an evolutionary biologist at Princeton University, that ...

Poaching likely created a generation of tuskless elephants, scientists say. Scientist are looking to see if poaching has altered the genetics of the herd. By Clark Bentson. January 16, 2019, 10:50 AM.

Ivory poaching has led to a "rapid evolution" of tuskless African elephants, as elephants without tusks were far more likely to survive during the height of the ivory trade, according to new research.

A tuskless elephant matriarch with her two calves in the Gorongosa national park in Mozambique. AP. He and his team were inspired to conduct the study after observing high rates of tuskless female ...

In Gorongosa in the 1970s, 18.5% of female elephants didn't have tusks. Now that number is 51%. Analysis from the study revealed that tuskless elephants are five times more likely to survive.

Ivory poaching in Africa drove the rapid evolution of tuskless elephants in some regions, but the good news is that increased protections from poachers are helping the pachyderms get their tusks ...

Sure enough, the researchers found that elephants born to tuskless mothers were more likely to be female (the gene is deadly in males), and about half of these daughters were tuskless.

The population of tuskless elephants has since declined to 33 percent in 2010. Advertisement. The absence of tusks is caused by a mutation in the X chromosome in elephants that is lethal to males, ...

Tusks are continuously growing incisors. Typically, adult elephant teeth comprise 12 premolars, 12 molars, and two tusks. These twin teeth are composed of four layers, the outermost being the enamel.

Tuskless elephants may evolve new problems. Human activity has affected elephants so much that a change in their genome has now become apparent, but being born tuskless is proving to be fatal for ...
